some issues with hand-controls and oculus-touch-controls

[giordyb]

I'm not sure if it's an issue with your component or with aframe 0.5.0 in general but I'm adding this issue here since it affects your component:

• both hand-controls and oculus-touch-controls require the raycaster to be set.
  to get the basic example to work I had to add
  raycaster="objects: #sphere" to the entity

• hand-controls: when I click the sphere the "click" event gets called twice instead of once. this does not happen with the oculus-touch-controls.

I'm also seeing the same problem with the raycaster needing to be set when using vive controllers. giordyb's workaround of adding the raycaster explicitly on the entity worked for me.

I'm not sure, but I think it may be a bug with aframe raycaster implementation where they check for objects being null to intersect with everything, but actually pass an empty string {''} as the default.

With hand-controls, I didn't need to add the raycaster explicitly but the "click" event was called twice instead of once. Considering it doesn't happen with vive-controls, I'm not sure the problem is with controller-cursor.

It's a bug with A-Frame aframevr/aframe#2379
